The Value of Uncertain Data

Evidence-based decision-making is a useful framework for the development of policies and practices to ensure water security, ecosystem resilience, and productive societies. The term “evidence-based” is gradually yielding to the term “data-driven” as focus shifts from specified data (i.e. fit-for purpose) to data discovery (i.e. big data) as the source of evidence.

The Economics of Hydrometric Data Quality

Data about water quantity and water quality are fundamental to some of the most important decisions made by engineers and in choices made by societies. Abundance and quality of water are critical factors in many aspects of our economy, our environment, and our social and physical well-being. It is the case than multiple water resources objectives must be simultaneously managed. The costs of sub-optimal water resources choices can be substantial. Uncertainty is antagonistic to optimization.

Mitigating Risk for Risk Mitigation: What L’Aquila Means for Water Monitoring

On October 22, 2012, six Italian scientists and a government official were sentenced to 6 years in jail, given lifetime bans on holding public office, and ordered to pay compensation of €7.8m in connection with the L’Aquila earthquake. The 6.3 magnitude earthquake injured over 1,000 people and resulted in 300 deaths. The judgment was based…

The Future of Water Data Sharing – Discoverable, Searchable and Accessible

The Open Geospatial Consortium (OGC) is seeking public comment on part 1 of the new WaterML 2.0 data standard for time-series data encoding Aquatic Informatics is actively participating in the Hydrological Domain Working Group, which has a mandate from both the OGC and the World Meteorological Organization (WMO), to explore issues of hydrological data interoperability….

Emerging Data Analysis & Production Techniques

Advances in communications and data management technologies have allowed data providers to meet the latent demand for hydrometric data in support of adaptive management of our water resources. Discharge is a derived variable for which considerable care is required to ensure reliable results. The hydrometric data production process has historically been managed on an annual…
